• MC3000 Controller Board

Bard part 8612-019 is an OEM MC3000 controller board used in Bard lead lag control applications, where the board manages staging and alternation between redundant HVAC units to balance runtime and maintain reliable operation. This control board is a direct-fit replacement that restores proper switching logic and system coordination when a failed or intermittent board causes uneven unit operation or control faults. Verify the part number on the existing board and confirm controller compatibility before ordering, since Bard literature and distributors note that newer MC3000 board numbers may supersede earlier versions.
